Anna commented on Nike Grind Safety Roller

Hi,
Sorry for not answering before.
The proposal is based on a product that is already on the market and this product works as a car safety barrier. Theoretically, this ensures that it is also a good solution for car drivers. However, it is true that the fact that I am changing the rollers’ material means that it needs to be tested again. The principal risk of this change, it is that Nike grind is not strong enough to behave as the actual plastic rollers do.

Hey Ezgi sorry for not answering before.
I think it’s a very interesting question. At the beginning I thought that by pouring the Nike grind materials inside a skin would be enough. That way, almost no energy was put into reusing the scattered polymers. However, as you mentioned, it is difficult to assure that in case of a crash they are not going to pollute the area of the accident.
What I think it could be a good solution is to melt the plastic again using the minimum amount of energy required to stick together the polymers. It may pollute a bit too but it would be easier to get rid of the rollers that have been damage. In addition, it can turn out that the skin is no longer required because the Nike grind materials are good enough to resist the UV radiation and be waterproof.
Thanks for encouraging me to keep up with the work!

The cost of the Safety Roller would be comparable to other available products in the market once the production technics in larger scales and the attaching system it’s defined.
There are many reasons that make me think that it can be competitive although it’s not completely developed.
Firstly, the material used to create the rollers use leftovers that otherwise would be discarded.
Secondly, the new system increases the safeness compared to traditional ones by absorbing shock energy and converting that energy into rotational energy.
Thirdly, if the alternative attaching system that its being develop proof to meet the requirements it would be able to be implemented on old structures that are already in good conditions but that doesn’t work well as a safety barriers. Meaning that less waste will be generated because the barrier won’t be replaced but improved.
Finally, but not less important it will increase the night visibility on roads.
Hope this gives you a better idea of the concept. Any other questions or suggestions are more than welcome. Thank you!
